according to the increased fungi contaminations and related damages, microbiologist's incentive in considering the fungal contaminations in human habitats had increased. some of fungi cause disease through production of toxins in animals as well as humans. since these toxins are not easily distinguishable, then it is crucial to study their characteristics. aspergillus are among the most importa...

in this paper, a 3d stochastic model has been presented to predict the coating thickness and porosity in a thermal spray coating process. different values of processing parameters were obtained. the model was developed on the basis of prescribed rules in calculating the splat size during the impact of individual droplets on the surface of the substrate. due to the thermal stresses produced duri...

The general economic development in Asia has resulted in the reallocation of sweet potato utilization between pig feed and starch processing. In China, which produces 85% of the world’s sweet potato, about 45% is fed to pigs. Vietnam, the second largest world producer, allocates 75% to pig feed since sweet potato cannot compete with cassava as a raw material. Papua, Indonesia, does not occupy a...

This pilot analysis was conducted with data from 52 conventional grow-out broiler flocks in a prospective field observational study in the southeastern United States during 2003-2006. Each flock was sampled for Salmonella 1 wk before the end of grow-out, upon arrival at the processing plant, and during processing (prior to and immediately after carcass chilling). The broiler litter was sampled ...

control of poultry feed microbial contamination could reduce carcass contamination at processing plants and resultin improvement of public health. in this study the effects of commercial blend of organic acids (salkil® and formycine®), formalin 37% and formaldehyde gas on morphology of intestinal mucosa and gut microflora in broilers were investigated. three hundreds 1-d-old chicks (ross 308) w...

in turkey, it is known that, wastes of fisheries processing plants released to the environment and only a bit of that assessed as fish meal or fish feed by a few plant. it is expected that with the evaluation of these wastes which rich in nutrient content by converted to the various commercial products (chitin, protein hydrolyzate, carotenoprotein and pıgment extraction etc.) to be beneficial i...

In this study, an artificial neural network was used to predict the minimum force required to single point incremental forming (SPIF) of thin sheets of Aluminium AA3003-O and calamine brass Cu67Zn33 alloy. Accordingly, the parameters for processing, i.e., step depth, the feed rate of the tool, spindle speed, wall angle, thickness of metal sheets and type of material were selected as input and t...

in this paper, modeling and optimization of fischer-tropsch synthesis is considered in a fixed-bed catalytic reactor using an industrial fe-cu-k catalyst. a one dimensional pseudo-homogenous plug flow model without axial dispersion is developed for converting syngas to heavy hydrocarbons. the effects of temperature, pressure, h2 to co ratio in feed stream, and co molar flow on the mass flow rat...

One of the factors which are usually difficult to be measured in mills is the grindability and distribution of feed under real situation and in a short time. In the condition of achieving a fast and convenient way to determine these parameters, the proper relationship between energy, hardness and particle size distribution can be obtained. Feed hardness is one of the most important factors in g...
